Cause
1. Change of the configuration
2. Short-circuit
Distance between sensor
and reflector is too large /
light beam is not completely
aligned to the reflector /
reflector is not suitable / Front
screen and/or reflector is con‐
taminated.

Measures
1. Adjustment of the configura‐
tion
2. Check electrical connections
Check sensing range / check
alignment / SICK reflector is
recommended / Cleaning of
the optical surfaces (sensor
and reflector).
